To compare the outcomes of polytetrafluoroethylene (PTFE)-covered and uncovered stents in patients with malignant superior vena cava syndrome.

From October 2008 to December 2010, 21 consecutive patients who underwent PTFE-covered stent placement were prospectively studied. Those data compared with data obtained by retrospectively studying 31 consecutive patients who underwent self-expanding uncovered stent placement from February 2004 to September 2008.

The groups did not differ with regard to age, sex, underlying disease, or location and extent of venous compromise. There were no significant differences in technical success (p > .999) and immediate clinical success (p > .999) between the two groups. There were no complications following stent placement in both groups. According to the Kaplan-Meier analysis, the cumulative stent patency of covered stents was significantly better than that of uncovered stents (p = .039). One patient in the covered stent group developed stent occlusion compared with ten patients in the uncovered stent group, with this difference being significant (Fisher exact test, p = .016). There was no significant difference in the patient survival between the groups (p = .865).

PTFE-covered stents were significantly superior to uncovered stents in terms of stent patency for endovascular treatment of patients with malignant superior vena cava syndrome.

PTFE-covered stents were significantly superior to uncovered stents in terms of stent patency for endovascular treatment of patients with malignant superior vena cava syndrome.
